By Monday morning, the broken glass had been swept from the rug, smashed chairs had been cleared away and other than a man quietly setting up for another event, the upstairs hall at the Club Luis de Camoes was silent.

It was a different scene on Saturday night when, surveillance video shows, a crowd of about 200 people had gathered for a baby shower when a beer bottle flew past a man’s head and nearly hit the bartender as the event erupted into a melee, police said. It was chaos, Stoughton police Executive Officer Robert Devine said Monday.

“It’s a shame,” he said.

Police are investigating whether alcohol was a primary factor in the brawl that police said put children at risk and required about 30 police officers from Stoughton and area departments to break it up. Four police officers suffered minor injuries, police said.

Nuno Silva, a 14-year member and former vice president of the club, said Monday he has never heard of anything like it at the club before.

“It’s a tough economy,” he said, “so we try to rent it outside our membership. It’s all usually controlled.”

The club rented the Porter Street function hall to a family from Brockton for the shower, who police said were not compliant when they responded.

Three men arrested in the melee pleaded not guilty Monday morning at Stoughton District Court. Patrick Cardoso Lopes, 24, Paulo Pires Depina, 24, and Aderito Lopes Deandrade, 22, all of Brockton, were released on $1,000 cash bail.

A 14-year-old also was arrested. He was to be arraigned this week in juvenile court in Dedham, police said.

All four were charged with disorderly conduct, resisting arrest and assault and battery on a police officer. Lopes, Deandrade, and the 14-year-old were also charged with obstruction of justice, a felony. Lopes also faces a charge of intimidation of a witness, a felony.

Lopes, Depina and Deandrade posted bail on Sunday. Prosecutors did not seek further bail Monday.

A pretrial hearing date was set for March 1. The men all declined to comment.

Devine said police are studying surveillance video to see if more charges should be filed. Video footage was not made available Monday. The club, which has no strikes against it, Devine said, is cooperating with the investigation.
